The most commonly occurring arrhythmia is:
A) Atrial fibrillation
B) Ventricular tachycardia
C) Bradycardia
D) Ventricular fibrillation - ✔✔✔ Correct Answer > A) Atrial fibrillation
Atrial fibrillation, often called AFib or AF, is the most common type of
treated heart arrhythmia. An arrhythmia is when the heart beats too
slowly, too fast, or in an irregular way.
What is the technique for prenatal diagnosis of chromosomal
abnormalities at 10 to 12 weeks' gestation?
A) Chorionic villus sampling
B) Amniocentesis
,C) Linkage analysis
D) Gene mapping - ✔✔✔ Correct Answer > A) Chorionic villus sampling
Amniocentesis is usually performed during the 15th week of
pregnancy or later. CVS is usually performed between the 10th and
13th weeks of pregnancy.
When explaining the types of adaptive immunity, the FNP student is
aware that:
A) Adaptive immunity is a cell-mediated immune response which is
B) Adaptive immunity is the level of immunity that all persons are born
with.
C) Adaptive immunity occurs when antibodies are passed from the
mother to the fetus.
D) Adaptive immunity occurs through immunization. - ✔✔✔ Correct Answer >
A) Adaptive immunity is a cell-mediated immune response which is
carried out by T cells and B cells.
There are two types of adaptive immunity responses: the cell-
mediated immune response, which is carried out by T cells, and the
humoral immune response, which is controlled by activated B cells
and antibodies.
What is the term for an error in which homologous chromosomes fail to
separate during meiosis or mitosis?
A) Polyploidy
,B) Nondisjunction
C) Aneuploidy
D) Translocation - ✔✔✔ Correct Answer > B) Nondisjunction
Nondisjunction means that a pair of homologous chromosomes has
failed to separate or segregate at anaphase so that both
chromosomes of the pair pass to the same daughter cell. This
probably occurs most commonly in meiosis, but it may occur in
mitosis to produce a mosaic individual.
In the most commonly seen form of Turner Syndrome, how is the X
chromosome affected?
A) Each cell has only one X chromosome?
B) Some cells have two X chromsomes, while the other cells have only
one.
C) Each cell has two X chromsomes, but part of the chromosome is
missing.
D) Each cell has an extra X chromosome - ✔✔✔ Correct Answer > A) Each cell
has only one X chromsome
45% of persons with Turner Syndrome have monosomy X meaning
there is only one copy of the X chromosome in each cell.
The FNP is assessing a newborn who is demonstrating a high-pitched
cry, microcephaly, hypertelorism, hypotonia, and a low birth weight.
The FNP would suspect which of the following genetic conditions?
, A) Down Syndrome
B) Cri du chat
C) Charge syndrome
D) Duncan disease - ✔✔✔ Correct Answer > B) Cri du chat
The clinical symptoms of cri du chat syndrome usually include a high-
pitched cat-like cry, mental retardation, delayed development,
distinctive facial features, small head size (microcephaly), widely-
spaced eyes (hypertelorism), low birth weight and weak muscle tone
(hypotonia) in infancy.
A woman has sustained a traumatic brain injury. She is able to follow
simple commands and can manipulate objects. Which term describes
this state?
A) Coma
B) Persistent vegetative state
C) Minimally conscious
D) Locked-in syndrome - ✔✔✔ Correct Answer > C) Minimally conscious
When responses to the environment are seen, the patient is said to be
in a minimally conscious state
Age and the admission of the Glasgow Coma Scale (GCS) are important
diagnostic factors in TBI. Which GCS score describes a severe TBI?
A) 13-15
